Answer
$d=-8$
Work Step by Step
We need to get the d alone. Thus, we cancel out the addition by subtracting 5 on both sides. This leaves us with the equation $-3/4 d=6$. d is being multiplied by a fraction, so we multiply both sides by the reciprocal of -3/4, -4/3, to get that $d=-8$. We plug -8 in for d and confirm that our answer is, indeed, correct.
